Sure, Jane Austen’s plucky Pride and Prejudice protagonist Elizabeth Bennet was pretty badass for her day. But what if she was given a sword, trained in martial arts, and forced to fend off periodic attacks from the undead roaming England’s Regency-era countryside? That is exactly the premise of Seth Grahame-Smith’s 2009 parody novel Pride and Prejudice and Zombies, which mashes up the characters and plot of the Austen classic with, well, zombies.

On Friday, the first trailer for the big-screen adaption appeared online with Lily James, Downton Abbey’s cousin Rose, portraying the beloved literary character. Directed by Burr Steers, the film also features Sam Riley (Control) as Mr. Darcy, Douglas Booth (Noah) as Mr. Bingley, and Suki Waterhouse and Bella Heathcote as Elizabeth’s sisters.
